I don't remember saying I believed it before, but I don't really have a reason to doubt you. I could have been tired or I could have been trying to say something else.
What I think is this: being a popular user gets you views, but no guarantee of upvotes. And yes, if people come to your page to view your memes, that's a help towards them upvoting (since they're there anyway), but it's no guarantee and I don't think people would upvote something they personally hate just because they like the user.
If Raydog made racist, offensive, or trolling memes (just to pick examples of what people generally don't like), people wouldn't upvote those.
